"Williams has dominated his level. Has good size, thick through the lower body. Plays with good power. Shows agility and a decent motor for a guy his size. Plays with good pad level, often gets under his opponents pads and drives them back. Locks out and disengages off of blocks well. When run goes away, does a good job of getting flat down the line of scrimmage to make the play."

"During his senior season, Williams broke the Missouri Southern sack record, and he finished with 27 sacks during his career at school. To make it clear, Williams is not just a sack artist, but a complete football player who can stop the run and get to the quarterback."

The 6-foot-3, 325-pounder has rare skills as an interior pass-rusher. NFL teams are always pressing to find interior defensive linemen who can put heat on the quarterback, and Williams has proven that he has that rare trait. The senior is Missouri Southern's career sack leader with 27.

Williams is very consistent, recording sacks in 9-of-12 games this year. He totaled 68 tackles, 16.5 tackles for a loss, 8.5 sacks and five forced fumbles in 2012.

To further illustrate his consistency, Williams had eight sacks as a junior and nine sacks as a sophomore. As with any prospect from a small school, the level of competition is a concern. Williams will be able to answer those doubts at the Senior Bowl. A good week there could send his stock skyrocketing.
